IMPROVEMENT IN PLOWS.

To all whom it may concern:

Be it known that I, GEO: W. COOPER, of Palmyra, in the county of Lee andState of Georgia, have invented a new and Improved Plow; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being bad to the annexed drawings, making a part ofthis specification, in which- Figure 1 is a side sectional view of myinvention, taken in the line 00 00, Fig. 2. Fig. 2 is a plan or top viewof the same with the handlebrace bisected and a portion removed.

Similar letters of reference indicate corresponding parts in the twofigures.

The object of this invention is to obtain a plow that may be constructedextremely light, be exceedingly strong and durable, and capable ofhavingits share readily adjusted to plow more or less deep, as desired.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a Hat steel bar, perfectly straight, to each side. of whicha steel bar, B, is secured. The bars B B have each a curved and straightportion. They are longer than A and project behind it a suitabledistance, perfectly straight and parallel with each other, as shownclearly in Fig. 2. The front parts of the bars B B and A are connectedfirmly together by the bolt a of the clevis C, and the back part of thebar A is connected to the bars B B by a bolt, 1). The bars B B arecurved or bowed at each side of the bar A at a point about opposite thecenter ofthelatter, as shown in Fig. 2. The three bars A B B, thusformed and connected together, constitute a very light, strong, anddurable beam.

The bolt b, which connects the back part of the bar A to the bars B B,also connects two bars D D to B B. These bars D D, from theplow-standard and between them, at a point near their lower ends, thefront end ofa curved bar, E, is secured by abolt, c. The back part ofbar E passes up between the back parts of the bars B B, and is securedthereto by a bolt, d, which passes through either of a series of holes 6in bar E.

To the lower parts of the bars D D, and at their front sides a share, F,is secured by a bolt, G, which passes between the bars D D. The share Fmay be of any desired form, and different kinds may be attached to thebars D D, as the nature of the work may require.

The bars D D and E may be of steel, and the handles H H may also be ofthin steel bars, connected at their front ends to the bar A by a bolt,0. The handles H H are connected by the upper part of a T-shaped bar, f,the lower end of said bar being connected to the bars B B by a bolt, 9.

The share F may be more or less inclined, so as to plow a greater orless depth by adjusting the bat-E higher orlower between the bars B B,the bars D D being allowed to turn or swing freely on the bolt 12.

The plow thus constructed is extremely strong and durable, there are noparts liable to break, for in case of the implement being suddenlyarrested in its movementsby astump,

stone, or obstruction of any kind the parts yield or give, and arethereby prevented from breaking.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is V The arrangement of the curved adjustablebar E and the swinging standard D D with the curved bars B B and beam A,all as herein shown and described, for the purpose set forth.

GEO. W. COOPER.
